About the guide
Holly leaved senecio is on the Alert List for Environmental Weeds, a list of 28 non-native plants that threaten biodiversity and cause other environmental damage. Although only in the early stages of establishment, these weeds have the potential to seriously degrade Australia's ecosystems.
Holly leaved senecio is native to the Cape region of South Africa. It is uncertain when the plant was introduced into Australia, but it was first recognised as naturalised in 1986 in the Albany district of Western Australia. Planted as an ornamental, its source was from a home garden adjacent to the Mt Adelaide and Mt Clarence nature reserve. Holly leaved senecio is now also found 20 km from the original infestation.
Holly leaved senecio is also a serious environmental weed in New Zealand where it has spread rapidly over the last 20 years. The plant is particularly invasive in open damp areas, and has the ability to dominate understorey vegetation in these conditions.
